Abstract (en)
This application discloses a method and system for determining a packet forwarding path, and a network node. The method includes: obtaining, by a first network node, a first segment identifier advertisement message, where the first segment identifier advertisement message includes a first segment identifier and a first flag bit, and the first segment identifier is corresponding to a second network node; determining, by the first network node, that the first flag bit indicates that a packet needs to be forwarded through the second network node; and generating, by the first network node, a first packet forwarding path, where the first packet forwarding path includes the second network node. According to the method, the first network node determines, by using a flag bit combined with a segment identifier, that a packet needs to be forwarded through a network node corresponding to the segment identifier, thereby ensuring that a packet forwarding path includes a key node in a network. This prevents data from being forwarded by bypassing the key node, and ensures network security.
